Caracterización de tetraploides y formación de híbridos triploides en tomate de cáscara

Abstract

RESUMEN El tomatillo (Physalis ixocarpa Brot.) es de los cultivos hortícolas más importantes de México, aunque presenta rendimientos bajos, debido a que su autoincompatibilidad impide la formación de líneas puras e híbridos. La formación de poliploides sobresalientes de tomatillo es una alternativa para aumentar rendimientos y calidad de fruto. En este trabajo se encontraron diferencias significativas (p<0.01) entre diploides y tetraploides para RTF, NF, PPF, DPF, DEF, FIR, SST, pH y VC. Los híbridos triploides, 2Tx13D y 11Tx21D mostraron heterosis y heterobeltiosis en todas las variables estudiadas. En rendimiento, el triploide 2Tx13D superó en 178.24% al 2T y 19.66% al 13D, el 11Tx21D superó en 145.76% y 0.39% al tetraploide y diploide, respectivamente. ABSTRACT The tomatillo (Physalis ixocarpa Brot.) is of major horticultural crops of Mexico, although it has low yields because your self-incompatibility prevents the formation of pure lines and hybrids. The polyploids formation outstanding of tomatillo, are an alternative to increase yields and fruit quality. In this work, was showed significant differences (p<0.01) between diploid and tetraploid in RTF, NF, PPF, DPF, DEF, FIR, TSS, pH and VC. Triploid hybrids 11Tx21D and 2Tx13D they showed heterosis and heterobeltiosis in all the variables studied. In yield, the triploid hybrid, 2Tx13D exceeded in 178.24% and 19.66% to parents 2T and 13D, meanwhile the hybrid 11Tx21D exceeded to the diploid and tetraploid in 0.39% and 145.76% respectively
